Hirsbrunner Euphonium (HBS series)
A scarce Swiss professional euphonium family associated with traditional small-shop construction, a 12-inch bell, and stepped-bore HBS-378 and HBS-479 variants.
Provenance under review. Reported as Switzerland, but the country of manufacture is not yet independently cited — the maker's page does not state one.

The verdict
Hirsbrunner belongs in a different buying conversation from a readily stocked Yamaha or Besson. These are uncommon professional instruments from a small Swiss maker, and the appeal is the individual horn’s response, voice, and craftsmanship—not the ease of comparing current retail packages.
The available maker material supports a 305 mm bell and stepped bore, with the HBS-479 identified as the larger-bore relative. Because the maker page is not reliably accessible and the valve-layout details still need direct documentation, this is a record to use as an orientation rather than a substitute for inspecting the instrument. On a used Hirsbrunner, verify the exact model, compression, valve condition, previous repairs, and the availability of compatible parts before discussing price.
- Who it's for
- Experienced players and collectors who can evaluate a specific instrument in person and value Hirsbrunner's distinctive small-maker character over easy dealer access.
- Known for
- Swiss manufacture, rich traditional tone, limited availability, and two closely related bore profiles rather than a broad mass-market lineup.
- Watch out
- Current factory documentation is difficult to retrieve, and several configuration details in this record are corroborated rather than directly captured. Condition, parts support, and the exact model matter greatly on a used example.
